SPECIFICATION forming part of Letters Patent No. 626,076, dated May so,1899. i Application iiled September 2.9, 1898. Serial No. 692,166. (Nomodel.)

T0 all whom it may concern:

Be it known that I, `JOHN CHRISTOPHER MOLLOY, of Cincinnati-,in thecounty of Hamilton and State of Ohio, have invented a new and usefulImprovement in Printing-Presses,

of which the following is a full, clear,`and eX- act description.

My invention relates particularly to improvements in job-printingpresses; and the object of the invention is to simplify such pressesand, furthermore, to so construct a press that a sheet or circular canbe simultaneously printed upon opposite sides andI whereby the feed ofthe paper from a continuous roll may be regulated to suit any size of4sheet that may require to be printed, they sheet after leaving one formand bei-ng printed on one side being automatically delivered to thesecond form,which will print upon the opposite side of the sheet,andwhile the second impression on the rst sheet is being made the firstimpression on a second sheet is simultaneously made. i

A further object of the invention is to provide a simple, durable, andeconomic devicel for feeding the :printed sheets at proper stages to thecutting device, means being providedi for adjusting said feed, as may bedemanded by the len'gth or sizeof the sheet to be pri-nted. Anotherobject of the invention is to pro` vide for independent inkingdevicesfor each of the chases and, furthermore, to provide a means whereby allofthe mechanism will be operated from a single driving-shaft.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointedout inthe claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, iu which similar characters of reference indicatecorresponding' parts iu all the figures.

I Fig. 7 is a longitudinal section through the ink-distributing rollersshown in Fig. G. Fig. S is a plan view of one end ofthe'inlI-distributing rollers shown iu Fig. 6,illnstrating the endmovement of said rollers.. Fig. 9 is a detail sectional View of thelower inking device adapted for use in connection with the lower chase.Fig. 10 is a detail sectional View of one end of the directing-rollerslocated on the carriage between the chases, illustrating one manner inwhich the said directing-rollers may be adjusted. Fig. 1l is an enlargeddetail View of a portion of the side ofthe carriage, illust-rating themanner in which the feed, mechanism for the printed sheet is conneotedwith the carriage. Fig. 12 is a plan view of that portion ot' the deviceshown in Fig. 11. Fig. 13 is an enlarged vertical longitudinal sectionthrough the two clamps and cutting device for the press,the forwardclamp being shown as closed and in position to feed the paper rearward,While the rear clamp is Fig. 14 is a transverse section takenpractically on the line 14 Lief Fig. 13 looking in direction of thearrow. Fig. 15 is a transverse section takenv practically on theline 1515 of Fig. 13 looking in the same direction as in the section shown inFig. 14, and Figs. 16, 17, and 18 are detail views of minor portions ofthe press.

The frame of the machine consists, primarily, of two side pieces A,which are bolted in any desired manner to a base of any desired Eachside piece at its forward end is provided with an uprightI lsection orextension A', the uprights A extending inward from. the main sidepieces, so thaty the inner faces of the uprights are beyond the plane ofthe inner faces of the main side pieces, as shown at o. in Figs. 1, 2,and 3.

,'Boxes 10 are located upon the depressed portions ct of the frame, andin the said boxes the main drive-shaft 11 is journaled, the saiddrive-shaft being provided at one end with a balance-wheel12 and at itsopposite end with fast and loose pulleys 13 and 14, as is particularlyshown in Figs. 4 and 5. A pinion 15 is secured upon the drive-shaft 11within the said frame, and below the drive-shaft the frame is connectedby a cross-bar 16, upon which a bearing 17 is formed, in which is lOOjournaled a short shaft 18, said shaft extending likewise to one side ofthe frame, and on this shaft a gear 19 is secured, which meshes with theaforesaid pinion 15,as shown in Fig. 2.

Each side piece of the frame is provided with a concaved surface a' nearits extension A', and a plain track a2 is formed at the upper edge ofeach side piece extending from the concavity a' to a point near the rearend of each side piece, as shown also in Figs. 1 and 2. The upperportions of the extensions A are more or less rounded or cylindrical,and at the rear of the extensions the said extensions are connected by abed B, adapted to receive a chase 20, and the said chase is held inposition by blocks or lugs 20, as shown in Fig. 5, and a suitable latch20). (Shown in the same figure.) The back portion of the bed 2O ispreferably strengthened by any suitable number of ribs 21.

In each side piece a depression 22 is formed, and the forward portion 23of the said depression is open, as shown in Figs. 1 and 2, while therear portion 24 of the depression is cylindrical or rounded at its lowersurface or that portion which faces the opening 23, and a part of thedepressed portion 24 usually extends upward adjacent to the inner facesof the sides A. The front edge ofthe depressed section 24 in each sidepiece is straight, and the two depressed sections are connected attheir-straight edges by a bed C, adapted to hold a chase 25, which chasemay be secured to its bed in like manner as the chase 20. The surface ofthe upper bed B that receives the chase faces the rear of the machine,while the corresponding surface of the lower bed C faces the forward endof the machine, and the lower bed is likewise strengthened at its backby suitable ribs 26. \Vhileboth of the beds B and C are vertical, theyare not in vertical alinement, as is particularly shown in Fig. 2.

A carriage D is pivoted by means of suitable pivot-pins (l in boxeslocated at the upper recessed portions a' of the side pieces, asillustrated in Fig. l. The carriage consists, preferably, of two sidepieces 27, which at the top are curved upwardly and rearwardly, while atthe bottom the said side pieces are curved downwardly and forwardly. Theupper portions of the side pieces are connected by a vertical partition2S, which partition is preferably provided with a concaved rear face,and upon the forward face of the partition 23 a platen B is removablyattached through the medium of screws or otherwise, as shown in Figs. 2and 5. The platen B' when the carriage is in printing position isadapted to be brought closely against the chase 20 in the upper bed I3.At the lower portion of the carriage D the side pieces are connected byby a second partition 29, preferably provided with ribs 30, 3l, and 32upon its back, and this latter partition is connected by a pitman 33with the said gear 19,1eceiving motion from the drive-shaf t 11. Therear face of thelower partition 29 is adapted to receive a platen C',which when the carriage is in printing position will be brought closelyto the lower chase C, as shown in Fig. 2. Guide or tension rollers arelikewise provided in the carriage, two of said rollers 34 and 35 being1ocated one above the other below the lower platen, while two sets ofrollers are located above the upper platen, one set of rollers 36 and 37being located one above the other adjacent to the upper edge of theplaten, while the rollers 38 and 39 of the otherset are morehorizontally located, as shown in Fig. 2. Two sets of directing-rollersare located between the two platens, two of the rollers 40 and 41 beinglocated below the upper platen B',while the other two rollers 42 and 43are located above the lower platen C. The roller 4l of one set and theroller 42 of the other set of directing-rollers are made adjustable, sothat the paper will pass between the adjustingrollers insuch length asto insure that portion of the sheet receiving an impression at the lowerchase being brought in proper registry to receive an impression upon itsopposite side at the upper chase. The adjustment of these rollers isshown in detail in Fig. 10, in which it will be observed that therollers are journaled in boxes 42 and 4l, the said boxes being made toslide in a slot 42", formed in a plate 411, one of which plates issecured to the inner face of each side of the carriage and upon theupper surface of the lower partition 29,aud the adjustment of therollers is accomplished through the medium of ascrew 42", held to turnin the plate 4l", the screw being provided with a right and with a lefthand threaded surface, one threaded surface passing through thejournal-box of one roller and the oppositely-threadedsurface beingpassed through the journalbox of the opposing roller. Under thisconstruction itis evident that a quick adjustment for the feed of thepaper from one chase to the other may be expeditiously and readilyaccomplished.

A curved slot 44 is longitudinally made in the upper edge of each sidepiece 27 of the carriage, near its rear edge, and the rear edges of theslotted portions of the carriage are provided with notches 45, as shown.in Fig. 2. The slots 44 are adapted to receive adjustingblocks 4G, thesaid adjusting-blocks being adapted to regulate the throw of feed andtension devices, to be hereinafterdescribed and particularly adapted tocarry the` printed sheets from the carriage to the cutters of the press.These blocks are of peculiar construction and are shown best i'n Figs.11 and 12, in which it will be observed that each block is substantiallyU-shaped, one member, Z2, extending outwardly through the slot 44, whilethe other member, b', extends across the notched surface of the carriageadjacent to the slot. The member b is provided with a recess 47 in itsinner or forward edge, and an adjust-ing screw 49 is carried through themember b into the recess 47, where it is swiv- IOO IIO

eled to a head 48, held to slide in the recess journaled in the blocks46, as shown in Figs.,

2 and 11.

The tension and feed device for carrying the printed sheets from theimpression portion of the press to the cutting device is designated as Eand comprises, as heretofore stated, the side arms 50, attached to theadjusting-blocks 46, upon which arms is held to slide adjacent to thecarrier a bar 52, and the said bar 52 carries a roller 53, the rollerbeing slightly above the arms 50. The central portion of the arms 50 isenlarged, and two rollers 54 and 55 are journaled one above the other atthe enlarged portions, as is also shown in Fig. 2. The sliding bar 52 isprovided With an upwardlyextending member 56 at its center, and acorresponding member is formed upon a bar 57, located between the centerof the arms 50 and their rear ends. The projection from the bar 57 isadapted to receive the unthreaded end of a screw 58, the threadedportion of the screw being made to pass through a suitable opening inthe projection 56 from the sliding bar 52. the medium of the said screwS the sliding bar may be carried toward or from the center of the armsof the feed mechanism E, so as to increase or decrease the distancebetween the guide-rollers 53 and 54, in order that the feed of thesheets to the cutting device may be regulated according to the length ofthe printed sheets. A feed-roller 59 is provided for the feed device E,and this roller is located below the lower edges of the side arms 50,the roller 59 being fulcrumed in links 59, which are pivotally attachedto the said side arms 50 of the feed device in front of the fixedcross-bar 57, as is also shown in Fig. V2. The object of pivotallysuspending the roller 59 from the side arms 50 is to take up the slackof the paper during the movement of the arms.

The feed device E is employed in connection with a clamp F, which clampis adapted to receive the paper and at the rearward movement of thecarrier D carry the said paper or sheets in direction of the cuttingdevice. This clamp F is shown in Figs. 1, 2, 13, and 14, and it consistsof a bottom bar 60, which extends from side to side of the frame of thepress, and the said bottom bar is provided at each end with a shoe 61,angular in cross-section, the said shoes being adapted to slide upon thetracks a2 at the upper portion of the sides of the frame, a portion ofeach shoe ext-ending downwardly at the inner faces of the side piecesand the second portion of the shoes extending over the upper or tracksurfaces of the said side pieces, as is clearly shown in Fig. 14, inwhich, however, the tracksurfaces of the side pieces are shown to eX-Through tend beyond the inner faces of the sides of the frame and. themembers of the shoes are so constructed as to receive between them theaforesaid projecting portions.

The base-bar of the clamp F is made to receive an elastic or yieldingsubstance 62, which may be smooth upon its upper face or corrugated, asdesired, and near each end of the bottom bar of the said clamp F anupward ly-extending arm 63 is formed at the rear edge of the said bottombar, as shown in Figs. 2,13, and 14. An upper bar 64 is provided for thesaid clamp F, and in the bottom portion of the upper bar an elastic oryielding substance 65 is located, adapted to face and when the machineis not in use to engage with the bottom yielding surface 62 of theclamp. The upper yielding surface 65 is usually of less width than thelower yielding surface, and the upper cross-bar 64 of the clamp issecured at each of its ends to a triangular head-plate 66, thecontracted portions of which plates eX- tend downward, and the saidhead-plates 66 at their upper rear ends are pivotally connected with thesaid arms 63 through the medium of suitable pivots 67, whereas the upperforward portions of the said head-plates are pivotally connected withconnecting-bars 68, which bars are in their turn lpivot-ally attached tothe links 59, carrying the pendent roller 59, belonging to the feeddevice E, as shown particularly in Fig. 2. The lower apexsections of thetriangular heads are pivotally attached to the rear ends of the sidearms 50 of the tension and feed device.

In order that the movement of the upper member of the clamp F may belimited, a

Inose 69 is formed at the lower forward edge of each head-bar 66, asshown indotted lines in Fig. 13, and each nose 69 is adapted when theupper member of the clamp is carried to its upper position to engagewith a limiting, wall of lugs 70, formed upon the shoes 6'1 for the saidclamp. In order that the paper or sheets may be supported betweentheclamp F anda second and rearwardly-located clamp G, that is placed infront of the cutting device, as shown in Figs. 2 and 13, a shaft 71 isjournaled in the lower ends of the arms 63, extending from the base ofthe forward clamp F, and the said shaft 71 is provided with a series ofattached peripherally-grooved pulleys 72, (shown best in Fig. 3,) whileadjacent to the rear clamp G, above mentioned, a shaft 74, similar' tothe shaft 71, is pivoted in suitable bearings attached to a part of thesecond clamp, the shaft 74 being provided'with peripherallygroovedpulleys 75, `correspondingly located to thepulleys 72, and at one end ofthe pulley-shaft 71 a ratchet-wheel 7 3 is secured, which is'adapted tobe engaged by a pawl 73, pivoted upon one of the slides 61 of the clampF, as .shown in Fig. 13. This pawl prevents the forward movement of theforward pulley-shaft 71 and permits 'a rearward movement of said shaft.

Endless belts 76 are carried over the pul- IOO IIC

leys "2 and 75, forming a support for the sheets 'of paper, since theupper portions of said belts are horizontal, and the belts 76 extenddownward from the pulleys 72 and 75 over pulleys 77, secured upon ashaft 78, the said shaft 78 being carried by arms 79, which arms arepivoted upon a shaft S0, which extends through the depressed sections 24of the side members of the frame, as shown particularly in Fig. 2. Thearms 79 are adapted to weight the belts 76 and hold them taut. Vhen thecarrier D moves rearwardly, the impressions having been made, theprinted sheet of paper is moved also rearwardly by reason of the clamp Fengaging the said paper between its yielding faces, since the rearwardmovement of the carrier causes a rearward movement of the feed device E,and the rearward movement of the feed device, through the medium of itsside arms 50, will canse the two members or jaws of the clamp to bebrought together, due to the connection of said arms with thehead-plates 66 of the upper member of the clamp. Consequently at therear movement of the said carrier the sheet of printed paper is carriedtoward the rear end of the machine and the dog or pawl 73 will preventthe shaft 7l moving forward, and as the shaft 7l approaches the shaft 74the tension or gravity arm 79 will draw the belts 76 downward,shortening their stretches between the two shafts, yet preserving saidstretches taut. In this manner the printed sheet is supported andassisted in its movement from the clamp F to the clamp G. Vhen thecarrier D, however, moves forward to effect other impressions, the sidearms 50 of the feed device, by rocking the head-plates 66 in .Thus atthe rearward movement of the clutch or clamp F it will not engage withthe paper, and the dog or pawl 73n will not prevent the shaft 7l fromturning. Consequently the belts 76 in the forward movement of thecarrier will not have any influence upon the sheets that may be abovethem, while at the same time the length of the upper stretches of thebelts is increased and the tension or gravity arln 79 is drawn upward.At this time the rear downward stretches of the belts 76 are heldstationary by clamping or brake devices, to be hereinafter described.

The inking device for the form of the upper chase is shown in Fig. 2 andlikewise in Figs. 6, 7, and S. This inking device consists of anink-distributing table Sl, adapted to receive ink froma fount suitablylocated. This table is provided with a convex upper surface and at oneof its ends has teeth 82 produced therein, as shown in Fig. S. The tableis provided with two supporting-arms 83, one at each end, and thesearms, as illustrated in Fig. 2, are mounted to turn upon a shaft St,carried from side to side of the extensions A of the frame of themachine. One arm is carried below the pivoted shaft Si, and theextension of this arm is attached to a link 85, which in its turn ispivotally connected with a crank-arm 86, secured upon a second shaft 87,also journaled in the extensions A of the sides of the frame. The shaft87 extends'through land beyond the outer faces of the extensions A' ofthe frame, and each end of the Shaft, as shown in Fig. l, is attached toan L-shaped or angle arm 88, the shorter member of each of the saidangle-arms S8 being connected by a pitman 89 with the sides of thecarrier D between the center of its sides and their upper ends. Thelonger member of each anglearm is provided with a longitudinal slot 89,and at the rear end of thev slotted portion of each angle-arm bearin gs90 are provided, through which bearings a rod 91 is loosely passed intothe slot, the rod 91 being provided with a head 93 at its forward end,adapted to travel on the side walls of the slot. Aspring 92 is coiledaround each rod 91, having bearing against the head 93 of the rod andthe adjacent bearing 90 for the rod. Each rod is pivotally connected atits rear end to a plate 94, in which plates ink-supplying rollers 95 arejournaled, the said rollers being adapted f to travel in the downwardmovement of the angle-armsalong the upper edges of the extensions A ofthe frame and over the type in the form of the upper chase, thismovement of the ink-supply device taking place at the rearward movementof the carrier D. At the forward movement of said carrier the inksupplydevice is carried forward to the dotted position shown in Fig. l.

The ink is mixed or equally distributed on the ink-table Sl through themedium of two rollers 96 and 97. (Shown in Figs. 6 and 8.) These rollers96 and 97 are mounted in boxes 98, the said boxes being pivotallyattached to the en ds of rocking .bars 99, one of said bars beinglocatedat the top upper edge of each of the extensions A' of the frame, beingattached to the said extensions by a central pivot-pin 100, as shownparticularly in Fig. 8. One end 'of one of the bars 99 is provided witha longitudinal slot 101, which longitudinal slot receives a pin 102,attached to a pinion 103, the said pinion, as shown particularly inFigs. 6 and 7, being mounted in one of the side extensions A of theframe, and the teeth of this pinion engage with the teeth 82 of the inktable or carrier Sl. Thus it will be observed that when the ink-tablepasses beneath the distributing-rollers 96 and 97 and the teeth of I thetable engage with the pinion 103 the rollers have parallel end movementin addition to their rotary movement, thus grinding and distributing theink on the upper surface of the table, from whence it can be taken bythe take-up or supply rollers 95, which in their turn convey the ink tothe type.

The inking mechanism for the form of the lower chase is substantiallyidentical with that provided for the form of the upper chase, exceptthat the inking mechanism for the form of the lower chase is located atand part of it is adapted to travel along the lower circular portion ofthe depressed section 24 in the side pieces A, as shown in Fig. 2. Theinksupply table 104 corresponds in construction to the table S1,heretofore described in connection with the form of the upper chase, thetable being carried by arms 105, pivoted on a shaft 106, mounted in thedepressed portions 24 of the side pieces of the frame, and one end ofone of the arms 105 is elongated to pivotally receive an end of a link107, which is pivotally attached to a crank-arm 108, secured to theshaft 80, heretofore mentioned, and as illustrated in Fig. 2. An anglearm or bar 109 is secured at the junction of its members at each side ofthe shaft outside of the said depressed section 24 ofthe frame, as shownin dotted lines in Fig. 2, and thisangle arm or bar 109 is of similarconstruction to the arm or bar SS, described in connection with the formof the upper chase, the rollers carried by the said arms or bars 109being arranged to travel across the table 104 and over the type in theform of the lower chase. The shorter member of each of the arms 109 ofthe ink' supply device is pivotally connected by a connecting-rod 110with the lower part of the sides of the carrier D, as shown in Figs. 1and 2. The table 104 is also provided with teeth 111 at one of its ends,and these teeth engagel with a pinion 112, corresponding to the pinion103 at the upper portion of the frame, the pinion 112 being mounted atthe bottom portion of the depressed side section 24, as shown in Figs. 1and 9. This pinion is provided also with a pin which enters a slot inabar 116, two of which bars are employed, one at each side of themachine, and the said bars 116 are pivoted at their centers to theaforesaid depressed surface 24 and act in like manner as the bars 99,described in connection with the inking apparatus for the form of theupperI chase; butthe bars 116 are rectangular, and the bearings 115forthe distributing-rollers 113 and 114 are located between the membersof the bars, the said bars being rectangular and of skeleton form, andthe bearings are held in place by suitable springs 117, as shown in Fig,9. The alteration in the shape of the bars 116 and the addition of thesprings 117 are made necessary by reason of the distributing-rollersfacing downwardly, the springs serving to keep the rollers in theirbearings. The movements of the inking devices for the form of the lowerchase are identical and in concert with the inking devices for the formof the Lipper chase, which movements have been particularly set forth.

The rear clamp or clutch G consists of a bed-plate 118, which extendsfrom side to side of the frame, the top of the bed-plate beingpreferably flush with the upper surface of the frame; but the saidbedfplate is provided at its rear edge with a longitudinally-located andupwardly-extending section 119, and the bed-plate is further provided ateach of its sides with a downwardly-extending section 120, as shown bestin Fig. 13. In the upper forward portion lof the bed-plate 11S alongitudinal strip 121 of rubber or a like material is placed, andtheupper section or jaw of the `said clamp or clutch consists of a bar 122,having a strip 123 of yielding material in its under face, whichyielding strip is adapted to register with the strip in the bed-plate,as is also shown in Fig. 13. The bar 122. of the upper member of theclamp o r clutchv is provided near each end with cars 124, which arepivotally attached to forward projections from the forward face of therear upper eX- tensions 119 of said bed-plate, as is also best shown inFig. 13. Preferably the side pieces of the frame are cut away at the topto receive the downwardly-extendin g portions 120 of the said bed-plate,and below the yielding strip 121 in the bed-plate of the second clamp orclutch G a shaft 126 is journaled in the lower side extensions 120, asshownin Figs. 13 and 15, and at the left-hand end of the shaft 126 acrank-arm 127 is attached, connected by a link 12S with the upper bar ormember 122 of the said clamp or clutch G. At the opposite or right-handend of the shaft 126 a disk 129 is secured. (Shown in detail in Fig. 16and as attached in Fig. 15.) This disk 129 is connected by a pitman 130with the right-hand end of the upper member of the clutch G. In theupper edge of the crankdisk 129 a peripheral recess 131 is made, whilein the lower peripheral portion of the crank-disk a series of teeth 132is produced. These teeth are adapted to mesh with the teeth of asegmental gear 138, provided with an attached shank 139, by means ofwhich it is pivoted to the outer side face of one side piece of theframe, asis likewise shown in Figs. 15 and 16. mounted on the right-handend of the shaft 126, and this crank-arm is provided with a stud orfinger 134, adapted to travel in the recess 131, the crank-arm beingconnected by a pitman 135 with a lever 136, pivoted by a pin 137,located between its center and upper end, the said pin being secured tothe outer face of the rear side of the frame, as shown in dotted linesin Fig. 1, and the lower end of the lever 136 is through the medium of aconnecting-rod 141 pivotally attached to the righthand side of thecarrier D, preferably at that point where the pitman 110 of tlie lowerinkin g device is likewise attached. A collar 141n is secured upon theright-hand end of the shaft 126, and a spring 141b is attached to thesaid collar and to the shank of the mutilated gear 138, the said springserving to exert tension on the upper member of the clamp or clutch Gwhen said member is open and when it is closed. The clamp or clutch G isopened and closed through the medium of the connectingrod 141, lever136, crank-disk 129, and the shaft 126, to which the crank-disk isattached, it being obvious that there is a slight lost motion by reasonof the finger 134 Ahaving t-o IOO A crank-arm 133 is loosely IIO travelsome distance in the recess 131 of the crank-disk before the said diskis moved, and this lost motion is provided for in order that the cuttingand delivery devices may be operated prior to the opening of theaforesaid clamp or clutch G. The clamp or clutch G is closed when thecarrier moves to printing position and is opened at the time that thecarrier moves from the chases, and the feed mechanism E operates tocarry the printed sheets rearward. The rear shaft 74, carrying theguide-pulleys 75, is journaled in the forward upper end portion of thelower extension of the bed-plate ofthe said rear clamp or clutch G, asshown in Fig. 13, and in the saine portion of the said extension of thebed-plate 11S a bar 142 is transversely secured, forming a portion of abrake for the belts 76, the rear face of the said bar being providedwith a yielding surface 143. This bar and its yielding surface are atthe forward side of the rear downward stretches of the guidebelts 76,and at the rear side of the said belts a second bar 144, provided withdownwardlyextending crank-arms 145, is pivotcd in the under extension120 of the bed-plate 11S of the rear clamp or clutch by means of a rod144, passed through the angular portion of the bar 144 at theintersection of the members thereof. The bar 144 is provided with ayielding forward face 146, and the horizontal members 145 of the angularbar 144 are so weighted as to keep the bar144 normally out of engagementwith the said belts 76, as shown in Fig.13.

The bars 142 and 144 constitute two jaws for the clamping or brakedevice for the belts '76, above referred to, and serve to hold the belts76 stationary during the time that the rear clamp or clutch G is closed,and the jaw 144is carried to the clamping or gripping position with thebelts 76 through the medium of cams 147, which are attached to the shaft126, operating the movable melnber of the clamp G, and these cams whenthe upper member of the said clutch is closed upon its lower memberengage with the rear surface of the movable jaw or bar 144 and forcesaid jaw or bar forward, and when the jaw or bar 144 is relieved fromengagement with the cams 147 the weighted arms or members 145, attachedto said jaw or bar, will carry it automatically out of engagement withthe said belts 76.

A metal plate 14S is fitted in the rear face of the upright memberorportion of the bedplate 11S, as shown in Fig. 4, and a'longitudinal slot149 is made in the said plate and likewise in the member 119, to whichthe plate is attached, as shown particularly in Fig. 13, the slot in themember having a fiat bottom and an inclined upper surface, and the upperedge of thc slot in the plate 148 is made a cutting edge. A standard 150is secured to the base of the machine and is made to extend upward atthe rear right-hand side thereof, and in the upper end of this standard150 and likewise in the uprightmember 119 of the bed-plate 11S a shaft151 is journaled,

to which one end of a delivery-table 152 is secured, the normal positionof which table is horizontally at the rear of the aforesaid member 119of the bed-plate 118, as shown in Figs. 1, 2, and 4. An arm 153 isloosclypivoted at its right-hand end upon the shaft 151 quite close tothe rear surface of the extension 119 of the bed-plate. The said arm isrecessed in its upper edge from a point near its pivot to a point nearits outer end, and within the said recess a ease or holder 154 ispivotcd, and a knife 155 is attached to the forward edge of the saidcase or holder, the knife being adapted to engage with the outer or rearface of the plate 148 at the rear of the machine, having a` cutting edge149, the knife 155 in operation passing the cutting edge 149 in suchmanner as to produce a shear cut, the paper being cut through the mediumof the two cutting-surfaces. At the rear or pivot end of theknife-carrying arm 153 an upwardly-extending horn 156 is located, andthe -knife is held against the blade 148 by means of a torsion-spring157, (shown best in Fig. 1S,) located in a recess near the pivot end ofthe knife-carrying arm, the spring being attached to the said arm and toone of the pivots of the knife-holder 154.

An angle-lever 158 is fulcrumed at the junction of its members upon therear face of the extension 119 of the bed-.plate 118, as shown in Figs.4 and 18, and the two members e and c' of this lever are out ofalinement, the outer member e being adapted to engage with the horn 156of the knife-carrier, and when the opposite member c' of the lever israised the member e will so act on the knife-carrying arm as to raisethe said arm and bring the knifeblade to the cutting position. The outermember e is engaged with the peripheral surface of the disk 159, whichdisk is provided with a cavity 160 in its peripheral surface, and whenthe member e' of the lever 15S is in the said cavity the knife will bein its lower or normal position; but after the member c has passed thesaid recess 160 the knife will be carried upward past thecntting-surface 149 of the plate 14S and held in an upper position untilthe recess 160 of the disk is again brought around to its normalposition. (Shown in Fig. 4.)

A pinion 161 is secured to the outcrface of the disk 160, and thispinion is engaged by the toothed surface of a segmental arm 162,fulcrumed upon the rear end of the righthand side of the frame, as shownin Fig. 2. rlhe segmental arm 162 is pivotally attached to a link 163,the link being in its turn pivotally connected with a crank-disk 164,secured upon a shaft 165, mounted upon the outer face of the rear sideof the frame, the shaft 165 at its forward end being provided with abeveled pinion 166. The beveled pinion 166 engages with a beveled gear167, provided with an attached spur-pinion 168,Which pinion is made tomesh with a gear 169, having a ratchet-wheel 170 secured to its outerlOO IIO

face, as shown in Figs. 1 and 2. A crankarm 172 is pivoted upon theshaft upon which vthe combined gear and ratchet-wheel169 and 170 aremounted, the said crank-arm carrying a dog 171, arranged for engagementwith the ratchet-wheel 170, and the said crankarm 172 is connected by allink 173 with the lower end of the lever 136.

While the rear clamp or clutch Gholds the paper at the commencement ofthe forward movelnent of the carrier, the aforesaid gearing operates thedisk 159, and consequently the shaft 151, to such an extent thattheknife will be carried tothe cutting position and the delivery-table willhave been carried to the dumping position and returned to its normalposition before the finger 134 shall have traveled the length of thegroove 131 in the crankdisk 129, operating the movable jaw'of the clutchG to engage with a surface of said crank-disk that will cause the diskto rotate in a direction to release the movable jaw of the said clutch Gfrom the paper, at which time the rearward movement of the carriage willtake place, and the forward clutch or clamp F will be closed, asheretofore described, enablingthe paper to be passed freely through therear clutch and through the opening in the upper extension 119 at theupper rear portion of the machine out upon the distributing-table, sothat at the commencement of the forward movement of the carrier thepaper will be delivered on the table to be cut. At each rearwardmovement of the carrier, as heretofore stated, the paper, which is in acontinuous sheet, is drawn upward from the lower form,bywhich it wasprinted upon one side, and delivered to the upper form, so that the sameportion of the sheet may be printed upon the opposite side at the nextprinting movement of the carrier. The roll 174, upon which the paper 176is wound, is mounted in suitable bearings 175, located at the bottomforward end of the machine, the roll being readily removable from itsbearings, and the paper 17 6 is carried rearward over a guideroller 177up between the lower guide-rollers 34 and 35 at the lower portion of thecarrier, thence upward in engagement with the printing-face of the lowerplaten C, then over and around the intermediate tension-rollers 42, 43,40, and 41 to an engagement with the printing-surface of the upperplaten B,thence in engagement with the two upper sets of guide-rollersin the carriage designated as 36, 37, 3S, and 39,) and from theserollers the paper is carried over the roller 51, carried by theadjustable blocks 46, thence over the roller 55, the adjustable roller53 forming a portion of the feed mechanism E, and over the rollers 54and 59 of said feed mechanism, thence between the jaws of the firstclamp or clutch F, over the upper stretches of the guide-belts 76, andbetween and through the jaws of the rear clamp or clutch G. Itis evidentthat at the rear or feeding movement of the feed device E the belts 76will assist in conducting the sheet to the second clutch G, since as therollers 71 and 74 are brought somewhat close together, as shown in Fig.1, the weight of the gravity-arms 79 will keep the belts 76 constantlytight and the shaft 71 will be prevented from turning by means of thepawl 73L engaging with the ratchet 73; but at the return movement of thefeed mechanism E and the carriage D, the clamp or clutch G having closedupon the paper and the clamp or clutch F having opened, thesupporting-belts 76 may return to their normal position, since the shaft71 will be free to turn, the pawl 73n not acting to hold theratchetwheel 73; but at this time the bars 142 and 144 will hold therear stretches of the belts 7G stationary, thus preventing thelengthening of the upper stretches interfering with the printed sheetsbeneath which they lie.

A belt-shifter 179 is used in connection with the fast and loose pulleysupon the drive-` shaft, said shifter being operated by a suitable lever180 at the front of the machine. A brake 178 .of any approvedconstruction is preferablyr employed for the t-runnions of the roll 174,upon which the paper 176 is wound, as shown in dotted lines in Figs. 1and 2.
